A.     One prediction of this hypothesis is that the Aquaticus maximus has better mobility, flexibility, and freedom of locomotion in comparison to the land and tree-dwelling species Aquaticus fidgetis allowing a restricted movement of the bones attached to the hip joints. In the land locomotion form, the acetabular surface is planar allowing better mobility on land (Stein et al., 2017). In the swimming form of the organism, the femur bone has a round head in comparison to the landforms having a straight rigid head of the femur bone mainly for locomotion and movement (John, 2016).
B.     There are 2 kinds of hips associated with the movement of animals or mammals. One type of hip is broad and sturdy in shape with the leg bones attached in the socket for maintaining the posture, balance, and stature of the organism on the land. The other type includes the smaller hip which is used for movement and locomotion by the organism. The...
